The Impact Data Recorder is a compact device with a sensor that records impact data when a vehicle is involved in an incident. Once it's fitted, you can forget about it, but correct installation can affect how useful the data is.
After an incident, officials add the data to an incident report to show where vehicles, equipment and circuits can be made safer. Day to day, you likely won't notice a difference, but an IDR will contribute to he overall safety for everyone on the track.
IDR installation
An IDR can be installed in various vehicle setups; for now, we will cover the most common vehicle types.
Where to install in a car
An IDR should be installed on the floor, as close to the centre of the cockpit as possible. For Formula cars, this could be under the seat; for Touring cars, this could be on the transmission tunnel.
As a general rule, we recommend that you:
Never install the device where it can get too hot.
Clean the surface before installing the device for a secure fit.
Point the arrow on the device towards the front of the car.
Where to install in a kart
Karting uses a dedicated IDR device that has been tuned for kart, it can't be interchanged with the car IDR device. Its mounting position is set out in Appendix 12 of the CIK-FIA Karting Technical Regulations, which must be adhered to.
Fit it and focus
Regardless of the vehicle type, setting up the IDR once it is in place is the same. Simply activate the FIA IDR app by scanning the QR code, then place your 'IDR Inside' sticker in a visible location outside the vehicle so officials know it's there.
